Question

我有Sprite对象，这是一个扑克筹码。当用户点击它时，出价增加。我正在提高对MouseUp活动的出价。但是，如果用户在对象/芯片外部开始点击，然后将鼠标拖到芯片上并执行MouseUp，则会触发映射到MouseUp的函数。如果点击从对象外部开始，我该如何防止它被触发。

this.addEventListener(MouseEvent.MOUSE_DOWN, pressChipDown)
this.addEventListener(MouseEvent.MOUSE_UP, pressChipUp)
this.addEventListener(MouseEvent.MOUSE_OUT, pressChipOut)



private function pressChipDown(e:MouseEvent):void
    {
        super.x = startX + 5;
        super.y = startY + 5;
    }

    private function pressChipUp(e:MouseEvent):void
    {
        increaseBid();
        super.x = startX;
        super.y = startY;
    }

    private function pressChipOut(e:MouseEvent):void
    {
        if(e.buttonDown) //if mouse button is down, move chip back but dont increase bid
        {
            pressChipUp(MouseEvent.MOUSE_OUT as MouseEvent)
        }
    }

滚动时，开始聆听鼠标按下并向上鼠标按下，如果向下按下，则为“假”

this.addeventlistener（MouseEvent.ROLL_OVER，onOver）

...

单击从对象外部开始时阻止MouseUp
